Indexing on ndarrays — NumPy v2.2 Manual

ndarrays can be indexed using the standard Python x[obj] syntax, where x is the array and obj the selection. There are different kinds of indexing available depending on obj: basic indexing, advanced indexing and field access. Most of the following examples show the use of indexing when referencing data in an array.

Python Arrays - W3Schools

Use the len() method to return the length of an array (the number of elements in an array). Return the number of elements in the cars array: Note: The length of an array is always one more than the highest array index. You can use the for in loop to loop through all the elements of an array. Print each item in the cars array:
